That's 260 degrees Celsius. Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
From the Wikipedia page on the World Sauna Championships, which exposed people to temperatures far lower than the above-advertised '500 Degrees Fahrenheit'.
You would think, but no. It was Fahrenheit. They rarely (if ever) went to 500 F though.
Look at the newspaper article: https://lemmy.zip/post/68972958/28002374 edmonton was canada, and they didnt start using metric for temp until the 70's I think.
Also the wikipedia article says this as well. Its F!
